Peripheral Vascular/Arterial Dz Flashcards
(46 cards)
bacteria causing Acute rheumatic fever
Group A streptococcus
What does acute rheumatic fever occur after
s. pyogenes pharyngitis
Diagnosis for Acute rheumatic fever
Jones critera (2 major or 1 major plus 2 minor and evidence of preceding S. pyogenes infection), antistryptolysin O titer, CRP, sed rate
Major manifestations of Acute Rheymatic Fever
SPECCial- subcutaneous nodules, polyarthritis, erythema marginatum, (Sydenhams) chorea, carditis
Minor manifestations of ARF
Fever, arthralgia, elevated ESR or CRP, EKG evidence of prolonged PR interval
Tx of ARF
TREAT STREP PHARYNGITIS. High dose salicylates, steroids
What is giant/temporal cell artiritis
vasculitis affecting large/medium arteries of head
cause of temporal cell arteritis
unknown, but most likely immune mediated
Patient presents with temporal headache that is bilateral, jaw pain, tongue hurts as well, and has been having difficulty seeing. complains of double vision. What are you suspicious of?
Giant/temporal cell arteritis
Patient presents with sandpaper like rash on stomach and polyarthritis. Also has fever, elevated ESR, and prolonged PR interval seen on EKG. What are you suspicious of?
ARF- check for evidence of preceding S. pyogenes infection with positive throat swab or raised antistreptolysin O titer
Diagnosis of temporal cell arteritis and tx
Biopsy with giant cells. Tx- long term corticosteroid- good prognosis with treatment
How much does aorta dilate in aortic aneurysm
dilation of aorta 1.5x its normal size
aortic aneurysm locations
aortic root aneurysm, thoracic aortic aneurysm, abdominal aortic aneurysm
symptoms in Aortic aneursym
ptnts asymptomatic until rupture
risk factors of aortic aneurysm
vascular disease, hypertension, dyslipidemia, tobacco abuse, marfan syndrome, ehlers-danlos
Diagnosis of aortic aneurysm
contrast CT, ultrasound
when is surgery indicated in aortic aneurysm
if rupture occurs. Or if AAA> or equal to 5.5 cm.
types of surgery in aortic aneurysm
open vs. endovascular repair
layers of tissue in aorta
tunica intima, media, and adventitia
aortic dissection
tear in inner wall of aorta causing blood to flow between muscular layers of tunica media, forcing layers apart
Patient presents with severe ripping/teraing with radiation to the back, HTN, tamponade, dyspnea, chest pain. Diagnosis?
aortic dissection
Diagnosis of aortic dissection
CXR- widening mediastinum, contrast CT, MRA (gold standard)
Classification of aortic dissection
Stanford A- proximal and Stanford B- distal. Stanford A- Debakey Type I and II. Stanford B- Debakey Type III
Debakey classification in aortic dissection
Debakey I includes ascending and descending aorta. Debakey II includes ascending only. Debakey Type III includes descending aorta only (distal Stanford B)
